Hi,

I have an entity like below.The example is a generic one and not the actual code

@entity
public class company
{
@Id
private int companyId
@onetoMany
private list<employee> employee;
}

@entity
public class employee
{

}

My requirement is that for a given companyId , I should be able to find out that employee entity is null or not null

I googled and found that there exist a method Persistence.getPersistenceUtil helps in finding out the same requirement.

I am using JPA in JAVA SE environment with eclipselink 2.3.2 as JPA provider. Problem 1 : getPersistenceUtil method does not exist when i am trying to call it on persistence class.

Problem 2 : What are the different ways to find that for the entity, which are the associated entities that exist
